7.- A small block of mass m=0.3 kg is placed inside an inverted cone that rotates about a vertical axis, so that the duration of one revolution of the cone is T. The walls of the cone form an angle B= 30° with the vertical. The coefficient of static friction between the block and the cone is us=0.4. If the block must be kept at a constant height h=0.5 m above the vertex of the cone, what maximum and minimum values can T have?

Rock Climber Sliding Down a Smooth Slab 9.6 m Hk =0.72 %3D 56° Consider the rock climber climbing on a smooth slab, as shown above: the coefficient of kinetic friction between the climber's rock shoes and the rock is 0.72 the belayer cannot see the climber who is out of sight beyond the edge of the slab the belayer cannot hear the climber because the wind is blowing very hard The climber loses his footing and slides down the slab from rest. How long after the climber loses his footing does the belayer realize she needs to catch the climber's fall? [answer: about 2.1 s] FNET = ma W = mg g = 9.81 m/s? Ax = vot + ½ at?

1. The 10-lb block has a speed of 4 ft/s when the force of F = (8t?) Ib is applied. Determine the velocity of the block when it moves s = 20 ft. The coefficient of kinetic friction at the surface is Uz = 0.15. Note: It's okay to use an online equation solver to calculate a number in this problem! v = 4 ft/s F = (8f) lb
